In situ GISAXS investigation of gold sputter deposition onto colloidal polymer templates
نویسندگان
چکیده
We investigated in situ the growth of a sputter-deposited gold film (sputtering rate R = 3.2 nm/min) on top of a pre-structured colloidal polymer template using grazing incidence small-angle X-ray scattering (GISAXS [5]). The underlying colloidal polymer template was deposited by using the novel technique of airbrush-spray coating, allowing for the installation of stripe-like trapezoidal pattern consisting of 3D hexagonally close-packed polystyrene (PS) colloids [6].

In Situ Ordering of FePt Thin Films by Using Ag / Si and Ag / Mn 3 Si / Ag / Si Templates
In situ ordering of FePt thin films by sputtering onto Ag/Si and Ag/Mn3Si/Ag/Si templates has been demonstrated. Due to the evolution from island-like to a continuous film structure as a function of Ag thickness, the ordering and orientation of the FePt films both change with Ag thickness. A continuous (002) Ag film results in a greater L10 phase formation with -axis oriented both perpendicular...
